Acknowledgment

APICS has developed these practice questions for the Detailed Scheduling and Planning module of the
Certified in Production and Inventory Management program. The 60 questions, similar to those found in the
certification exam, were compiled by the Detailed Scheduling and Planning Committee of the Curricula and
Certification Council. The practice questions are accompanied by an answer key and text references for
additional study.

APICS acknowledges the Detailed Scheduling and Planning Committee for its contributions to this
resource.

Important Information Regarding these Practice Questions

One important way to prepare for the APICS CPIM examinations is to simulate the test experience by taking a
series of practice questions. One of the benefits of using the practice questions is familiarizing yourself with
the types of questions encountered in an actual APICS certification examination. There is no correlation
between the number of practice questions you answer correctly and your success under actual examination
conditions, but your understanding of typical question formats can make the actual examination less stressful.

Please be aware that these practice questions have been retired from previous examinations. In most cases,
the questions had been used an optimal number of times and were replaced by questions that had enjoyed
less exposure. For this reason, the questions may not have been developed using the references currently
cited in the APICS Examination Content Manual as primary or additional references. The questions
themselves have been reviewed for currency by the appropriate committee of the APICS Curricula and
Certification Council.

The practice questions in this publication have been selected to represent the topical distribution of the
questions that you can expect to encounter in the examination. To assist you in a general understanding of
how test questions are related to the reference materials used in their creation, the answer key provides the
page numbers of the source reference material. However, unless they are identified in the current Examination
Content Manual, do not assume that the references listed in this publication are appropriate for use as study
materials.
